Description

The VL53L5CX is a state of the art, Time-of-Flight (ToF), multizone ranging sensor enhancing the ST FlightSense

product family. Housed in a miniature reflowable package, it integrates a SPAD array, physical infrared filters, and

diffractive optical elements (DOE) to achieve the best ranging performance in various ambient lighting conditions

with a range of cover glass materials.

The use of a DOE above the vertical cavity surface emitting laser (VCSEL) allows a square FoV to be projected

onto the scene. The reflection of this light is focused by the receiver lens onto a SPAD array.

Unlike conventional IR sensors, the VL53L5CX uses ST's latest generation, direct ToF technology which allows

absolute distance measurement whatever the target color and reflectance. It provides accurate ranging up to 400

cm and can work at fast speeds (60 Hz), which makes it the fastest, multizone, miniature ToF sensor on the

market.

Multizone distance measurements are possible up to 8x8 zones with a wide 63 ° diagonal FoV which can be

reduced by software

Thanks to ST Histogram patented algorithms, the VL53L5CX is able to detect different objects within the FoV. The

Histogram also provides immunity to cover glass crosstalk beyond 60 cm.

Applications

? Scene understanding. Multizone and multi-object distance detection enables 3D

room mapping and obstacle detection for robotics applications

? Wide FoV and multizone scanning allows content management (load in trucks,

tanks, waste bins)

? Gesture recognition

? Liquid level control

? Keystone correction for video projectors

? Laser assisted autofocus (LAF). Enhances the camera AF system speed and

robustness especially in difficult low light or low contrast scenes

? Augmented reality/virtual reality (AR/VR) enhancement. Dual camera

stereoscopy and 3D depth assistance thanks to multizone distance

measurement

? Smart buildings and smart lighting (user detection to wake up devices)

? IoT (user and object detection)

? Video focus tracking. 60 Hz ranging allows optimization of continuous focus
